You can probably pick up common thread from reading my previous answers as to what the Friesian needs from the human. This really applies to any breed but I think in the case of the Friesian there are a few things to be aware of. Firstly, you need to build a high level of feel on the ground, you need to do things in a slow methodical fashion giving the horse plenty of time to soak on things. Be aware if you are being crowded but don’t over react and force the horse outside your bubble, do this in increments. Try not to betray the Firesians natural curiosity to be with you. Finally, be prepared to get some form of ‘try’ from your horse when asking for a movement, don’t settle for ‘nothing’ as the Friesian can build on this really quickly and before you know it you can’t do anything.
